摘要
The main intention of this study is to investigate the cyclic behavior of bare/composite beam-to-Hollow Structural Section (HSS) column connections. The unique characteristic of beam-to-HSS column connections is the out-of-plane (OOP) deformation of the HSS column flange at the beam web-to-column flange interface which can reduce contribution of the connection web to the overall resistance of the connection. To explore effect of the column flange OOP deformation, performance of three connection types, namely composite beam-to-HSS column connection, composite beam-to-HSS column connection with slab-column gap, and bare beam-to-HSS column connections are evaluated. For each connection type, two column axial loads and four column's width-to-thickness ratios are considered. Totally 24 connections are investigated using pre-validated 3D Finite Element (FE) simulations. FE models are able to simulate low-cycle fatigue and post-rupture behavior of the connection. Comprehensive global and local responses are presented and discussed. It is found that column compactness, i.e. column's width-to-thickness ratio has considerable effect on maximum moment capacity, rotation capacity, postrupture residual capacity and energy dissipation capability of the connection. These results enrich available database on cyclic behavior of beam-to-HSS columns.
